Ixigo app is crashing

Are you sure you are using this on an iPhone 5S? If you are then it must be a very old version of the app because according to https://apps.apple.com/us/app/ixigo-flight-hotel-booking/id418128294 the current version of the app requires iOS 17 or higher which your device cannot possibly run. It is possible your old version can not longer interface with the services at the other end and is crashing because of that.

Here are other things you can try:

Have you restarted your device? That sometimes clears up odd issues.
